Problems solved by technology

Therefore, the demand for bletilla striata in the market is very strong. In addition, in recent years, wild bletilla striata has been excessively excavated in most parts of my country, resulting in a sharp decrease in its natural resources. It is on the verge of extinction and has been listed as a key protected wild plant by the state. One, in order to protect wild Bletilla striata resources, it is imperative to artificially breed and cultivate Bletilla striata. However, although Bletilla striata produces a large number of seeds, because the seeds do not have endosperm, the conditions for germination are harsh, making it difficult for seeds to germinate and grow under natural conditions. , even if seedlings can grow, the seedlings are extremely sensitive to environmental conditions and grow slowly, making the cultivation of Bletilla striata seedlings more difficult
Apparently, the common cultivation method of Bletilla striata mainly adopts rhizome propagation and division propagation. Both of the above two cultivation methods have the characteristics of low yield, poor quality, long planting cycle, low reproduction efficiency, and large seed consumption, and the growth rate is very low. The period is generally more than 5 years, which makes the early planting cost high, the economic benefits are slow, and the risk of investment is high, which seriously restricts the development bottleneck of large-scale planting of Bletilla striata. In addition, long-term multi-generation asexual reproduction is prone to seedling failure. degeneration, the medicinal value of bletilla striata is also weakened

Embodiment 1

[0018] The concrete steps of this embodiment are as follows:

[0019] ① Seedling propagation: seedling propagation adopts the cultivation method of tissue culture propagation,

[0020] a. Seed selection: select wild bletilla striata plants that are growing vigorously, and use artificial assistance to carry out cross-pollination or pollination between flowers of different plants during the flowering period. After 4 to 6 months, collect mature and full capsules as exogenous seeds for tissue culture. Implant;

[0021] b. Seedling cultivation: add 0.5% volume ratio of EM original dew to the pre-prepared tissue culture solution, then soak the seeds inside the capsule in povidone iodine for 3-4 minutes, rinse with sterile water for 2-4 times Blot the water on the surface with sterile paper, and finally inoculate the sterilized seeds into the tissue culture medium, adjust the temperature, humidity and light reasonably, and germinate new shoots within 15 days;

Abstract

The invention discloses a bletilla striata large-scale high-yield cultivation method. The method includes the steps of seed breeding, hardening, transplanting to a field, growth management, second year growth management and harvesting. The bletilla striata large-scale high-yield cultivation method has the advantages that the microbial technology and the ecological cultivation technology are combined, EM (Effective Microorganisms) is used for quickly accelerating the plant growth and decomposing residual farm chemical for further greatly shortening the planting period and improving the yield of bletilla striata. Compared with traditional cultivation methods, the planting period of bletilla striata is shortened for1 to 2 years and can be harvested in 3 years, the harvested bletilla striata is big in root and bright in color, and the yield per mu (one mu equals about 1.667square meters) of the bletilla striata is two to three times of that in traditional root cultivation, so that the risk of investment is greatly reduced, the early planting investment cost is low, the high economic benefit is achieved quickly, the non-polluting effect is obtained, and the conditions of industrialized and large-scale bletilla striata planting are met. The bletilla striata large-scale high-yield cultivation method is easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of planting Chinese herbal medicines, and in particular relates to a large-scale and high-yield cultivation method for bletilla striata. Background technique [0002] Bletilla striata is a perennial herbaceous plant of the genus Bletilla striata in the family Orchidaceae, mainly distributed in Henan, Shanxi, Sichuan, Guizhou, Yunnan and other places in my country. Bletilla striata is used as a tuber, which is recorded in "Shen Nong's Herbal Classic". It has the effects of nourishing the lung, reducing swelling, promoting muscle growth, and stopping bleeding. and other symptoms, in addition, Bletilla striata has gorgeous flowers and is also a good landscape plant. Therefore, the demand for bletilla striata in the market is very strong. In addition, in recent years, wild bletilla striata has been excessively excavated in most parts of my country, resulting in a sharp decrease in its natural resources. It is o...
